Bring back Spotify support for speakers

People have invested a lot of money in this audio equipment, just to be told to upgrade.

Spotify is removing itself from a number of home audio speakers and receivers from the likes of Onkyo, Denon, Marantz, Bang & Olufsen, Pioneer, and Yamaha. Some devices are losing Spotify integration completely, while others will require firmware updates if users want to continue receiving built-in access to their music. Some of the products in question were once all able to independently play Spotify over the internet — no smartphone required.
